The high-performance, low-power Microchip 8-bit AVR® RISC-based microcontroller combines 32 KB ISP Flash memory with read-while-write capabilities, 1 KB EEPROM, 1 KB SRAM, 22 general purpose I/O lines, 32 general purpose working registers, two flexible timer/counters with compare modes and PWM, USART, programmable watchdog timer with internal oscillator, SPI serial port, debugWIRE interface for on-chip debugging and programming, and five software selectable power saving modes. The device operates between 2.7-5.5 volts.
By executing powerful instructions in a single clock cycle, the device achieves throughputs approaching one MIPS per MHz, balancing power consumption and processing speed.
Additional Features
USB 2.0 Full-speed Device Module with Interrupt on Transfer Completion
Complies fully with Universal Serial Bus Specification REV 2.0
48 MHz PLL for Full-speed Bus Operation : data transfer rates at 12 Mbit/s
Fully independant 176 bytes USB DPRAM for endpoint memory allocation
Endpoint 0 for Control Transfers: from 8 up to 64-bytes
4 Programmable Endpoints:
IN or Out Directions
Bulk, Interrupt and IsochronousTransfers
Programmable maximum packet size from 8 to 64 bytes
Programmable single or double buffer
Suspend/Resume Interrupts
Microcontroller reset on USB Bus Reset without detach
USB Bus Disconnection on Microcontroller Request
